re: Weapons sales
"We are by far the largest supplier of arms to the third world but we are not by a long shot the only supplier and I have no doubt that a USA decision to curtail sales would be met with glee from UK, France, Russia and other eastern Europe nations."
I would assume that US weapons wouldn't be as cheap and therefore less attractive to third world countries. It seems to me the US mostly sells weapons to non-third world countries, e.g. to places like Saudi Arabia or Israel buying nearly top of the line fighter jets. Also the US has lots of regulations which would inhibit sales to various dangerous and unstable countries. Therefore I wonder if you have any evidence which supports "We are by far the largest supplier of arms to the third world".
